Specification of Letters Patent.

Patented June 23, 1908.

Application filed July 17, 1907. Serial N02 384,172.

Be it known that I, JAMES G. HEASLET, a citizen of the United States, and a resident of Detroit, in the county of l/Vayne and'St'ate of Michigan, (whose post-office address is 820 West Warren avenue, Detroit, Michigan,)

have invented certain new and useful'Im-- rovements in Clutches, of which the follow 1ng is a full, clear, and exact description,v

whereby and skilled in the art may make and use the same.

The invention,.as indicated by its title, re-

1 lates to clutches, and more particularly to a s ecial type of such devices known as disk utches.

The object of the invention is to provide a clutch which will firmly unite two sections of a shaft under certain conditions, but will per-' mit absolutely free running of one of the sections with reference .to the other when released.

It further provides for a'slip between the rotating parts when partially released. a A further object is to provide a clutch in which the end thrust between the clutch members is self-contained within the clutch.

tively heavy clutch drum or fly wheel'which is borne upon one end of a shaft projected Within a'tubular shaft section. The parts are completely inclosed and arranged to be run in, a bath of oil, their dispositionbeing such that the end thrust in the clutchin and releasing movements which" 'ordinari y in cone clutches exerts a considerable endv thrust between the two'shaft I sections, is entirely eliminated. I

' In'the accompanying drawings, numeral denotes an engine shaft having a collar 2 and a reduced shaft sectionB pro ecting beyond the collar. concentrically arranged with reference to the collar 2 is a fly wheel 4 of considerable weight, having a rearwardly extended flange 5." This fly wheel 4 is se-" To the rear face of the flange 5 is secured a 'encefito each other.

disk or plate 9 which forms a support for the clutch levers and their operating mechanism.

This plate 9 serves as a cover, completely inclosing the rearface of the clutch, and pre venting the escape of oil or other lubricant, as well'as preventing the ingress of dirt. Ex-

tendin within thereceptacle thus formed, is

a tubu ar sleevelO. which terminates at its outer end in a universal yoke joint 11. This sleeve'of course, surrounds the reduced shaft section 3, and intermediate the two there is'a sleeve 12. This is preferably of bronze, and

is pressed into the tubular-shaft section 10.

The inner end of the tubular-shaft 10 terminates in a flange 13 provided with seats 14 in which are firmly riveted steel disks 15. These disks are of nearly equal diameter with the inside diameter of the fly wheel and projectbetween bronze rings 1'61718, the

rings 16 and 18 lying on the outside surfaces of the two steel disks, while the ring '17 is interposed between them. -These rings may move axially, but are prevented from a relative rotation with reference to the fly wheel by keys 19 formed to engage keyways 20. These keys are arranged u on the end of screw threaded studs 21 which are inserted sleeve or nipple-27 'andupon the end adja-' cent to their springs, they are rounded as at 28-, to form a bearing against the clutch disk 18. It will'be noted, that this disk has a v slight cam uponits face adjacent to gthe operating levers 24 in order to provide easy and free movement of the arts with refer- The flbating sleeve or nipple 27 is nicely fitted about the shaft section and opening of the late or disk 9, and

upon being moved axial y, controls the action of thelevers 24-with reference to the clutch-rings and disks. The springs 22 are of such a tension that normally rings 18 are firmly ressed against the steel disks 16, and thus t e two' shaft sections are firmly united and they rotate in unison. .To release the clutch, a pedal or lever 30secured to a shaft 31 and bearinga yoke 32 may be pressed forward until itsTolls' 33 force the the bronze floating sleeve or nipple 27 inward a sufficient distance to depress the springs 22 and release the clutch rings and'disks.

It will be noted that the tubular shaft 10' and nipple 27 are what might be termed floating members, and of course when the clutch rings and disks are disengaged, the friction between the rotating parts is not sufficient to move the tubular shaft section 10.

It is obvious that the details of the various parts might be varied to a considerable extent without departing from the spirit 'or intent ofthe invention, and in fact the clutchiIig arts might be so arranged with reference to tie clutch levers that it would require a depression of the lever 30 to engage the parts instead of disengaging themf What I claim as my invention and desire to secure by Letters Patent is 1. In combination in a clutch, a driving member, a driven member, a series of rings having an axial movement with reference to said. members, clutch disks mounted upon the driven member and projecting between the-rings a plurality of resilient members for compressing the rings against the disks, and

' a plurality of levers cooperating with the respective resilient members.

2; In combination in a clutch, a driving member, a driven membe'r, a series of rings havin an axial movement with reference to said members, clutch 'disks mounted upon the driven member and projecting between' the rings a plurality of resilient members for compressing the rings against the disks, a plurality of levers cooperating with the respective resilient members, and means for releasing the rings and disks.

3. In combination in a clutch, a driving member, a driven member, a series ofrings carried by the driving member, a series of disks borne upon a driven member and lying clutch drum borne u onsaid'shaft and pro-- vided with an exten ed flange, a plurality of between the rings of the driving member, a plurality of means for normally engaging the rings and disks, each of said means including a spring cushion and a lever,'and a common levers.

means for controlling the position of' said 4. In combination in a clutch, '.afi shaft, a

j clutch drum borne upon the shaft" and provided with arrearwardly extending flange, a plate or disk secured to said flange and provided with spring cups and with springs arranged in said cups, levers pivoted to said plate and having one end. extending over the spring cups and with their op' osite ends resting upon a floating sleeve, an means for moving said sleeve and levers against the tension of the springs borne in saidspring cups.

5. In combination in a clutch, a driving member, provided with a rearwardly extending flange, a plate or disk secured to saidflange, and rovided with means of attachment for a p urality of resilient compressors, said compressors arranged concentrically with reference to the center of the driving member, a plurality of'levers pivoted to said ,plate and having one end actuated plurality of plates having grooves engaging said guides for an axial movement with reference to the shaft and a'driven member provided with lates cooperating with said axially movable, disks, and means for compressing said disks with reference to the plates of the driven member.

7. In combination in a clutch, a driving member provided with an extended flange, a plate or disk secured to said flange,-a-' lurality ofresilient members about'said concentrically arranged Withreference tothe centerof the driving member, a plurality of pivoted levers, each having. one end acted upon by the respective resilient members, and a common controlling means appurtenant to the opposite ends of saidlever's for varying the 'e ect of the respective resilient members.

8; In combination in aclutch, a shaft, a
